Skype for Business Integration with CME

Hi,

I need to integrate skype with CME for simultaneous ringing feature, like if someone calls on my extension then it rings at skype on the same time as  well.

what I have done is as below.

 dial-peer voice 3302 voip
translation-profile outgoing SKYPE
destination-pattern 488925..$
notify redirect ip2pots
session protocol sipv2
session target ipv4:10.106.5.58:5068
session transport tcp
incoming called-number 488925..$
voice-class codec 3302
dtmf-relay rtp-nte
no vad

!

voice translation-rule 4889
rule 1 /4889\(....\)/ /\1/
!
!
voice translation-profile SKYPE
translate called 4889

!

ephone-dn 76
number 2576
label 2576
description 2576
name user-1
mobility
snr 48892576 delay 0 timeout 15
hold-alert 30 originator

 

 

Now if I am calling from this skype profile to other skype profiles that works but when i am calling extension from this skype profile it is not working also if i dial extension 2576 it does not rings on skype.
If anyone can help on this please.

What is the CME version ? Is the ephone-dn 76 assigned to a phone or not ? If not then you are leveraging virtual SNR DN feature. If your CME version is earlier than 9.0, you won't be able to do this.

Hi,

the ephone-dn is associated to a phone which is already registered and working

basically we are having multiple CME/CUCM so that is why we are looking to implement this feature.

ios version is 15.5(3)M2

CME version 10.5

2921 platform

Hi,

 

still my issue is not solved can you check and advise?

If you dial "48892576" from an IP Phone, does the call go through ?

no it does not goes.

Ok, so SNR won't work. Let's get this fixed first.
From an IP Phone make a test call to "48892576" and enable the following -

debug ccsip message
debug ccsip error
debug voice ccapi inout
debug voip dialpeer
debug voip translation

Hi Nipun,

If I am dialing 48892576 from another ip phone registered on the same call manager as 2576 then it is giving a busy tone, but from other call manager(CME/CUCM) which are having dial-peer for this call manager with destination-pattern as 25.. it is not going thur, attached are the debugs when I called 48892576 from the same call manager, please have a look and let me know what to do.

Hi Nipun,

Did you got any chance to check this issue?

Checked the logs .. Gateway seems to be getting SIP message stating that "404 No matching rule has been found in the dial plan for the called number."

 

better to check Skype Side for this as when sending the 4 digit number 2576 To 10.106.5.58 you are getting the message.

 

I did not got your point, by the way skype is having the complete number since it is an analog line so the number is 025565xxx then extension 2576

 

if i understand it correctly you are saying that the skype should have number 48892576 for this user...correct me if i am wrong

Call is extended to Skype but the mediation server is sending a 404 post a 183 -

Call is routing via 3302 dial peer -

Called Number=2576(TON=Unknown, NPI=Unknown), Calling Translated=FALSE,
Subscriber Type Str=RegularLine, FinalDestinationFlag=FALSE, Outgoing Dial-peer=3302, Call Count On=FALSE,

Translation takes effect to convert the number to 4 digit before extending the call -

Jun 27 05:29:33.228: //-1/E76BA684ACAF/RXRULE/sed_subst: Successful substitution; pattern=48892576 matchPattern=4889(....) replacePattern=\1 replaced pattern=2576

Is this the way it should be ?

Yes, but skype is not having the number as 48892576 infact it is having the number in the below format

0255652xx;ext:2576 

i guess it should be only 48892576

let me know if i am saying it correct
